But the point would apply to any economy, however complex, and is not as simple-minded as it sounds. For another example: in a market economy that produces n different kinds of goods and services, if we know the production of n-1 kinds of goods and we know the production possibility frontier, then we can figure out the production of the remaining good or service. This amount will simply be all that we can produce with the resources left over from the production of the other n-1 kinds.
